The LCM of 770,724,380,778,252 is 18541506060.
Find LCM of 770,724,380,778,252 with Prime Factorization
| 2 | 770, 724, 380, 778, 252 |
| 2 | 385, 362, 190, 389, 126 |
| 5 | 385, 181, 95, 389, 63 |
| 7 | 77, 181, 19, 389, 63 |
| 11, 181, 19, 389, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 11 x 181 x 19 x 389 x 9 = 18541506060
Therefore, the lowest common multiple of 770,724,380,778,252 is 18541506060.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
770 x 724 x 380 x 778 x 252 = 41532973574400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
724 : 1, 2, 4, 181, 362, 724
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
778 : 1, 2, 389, 778
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,724,380,778,252, is 2.
Now, the common factors can be found like this.
770:2x 5x 7x 11
724:2x 2x 181
380:2x 2x 5x 19
778:2x 389
252:2x 2x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 5x 7 = 1120
Therefore, the value for common factors is 1120.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 41532973574400/(2x1120)
LCM = 41532973574400/2240
LCM = 18541506060
Thus, we can understand that the LCM of 770,724,380,778,252 is 18541506060.
